I am writing here because my problem involves many tools.
I have been trying to make extremely compact mp3's for download.
$lame PO_audio.wav -m m -b 8 PO_audio-low.mp3
LAME version 3.93 MMX (
http://www.mp3dev.org/)
CPU features: i387, MMX (ASM used), SIMD
Autoconverting from stereo to mono. Setting encoding to mono mode.
Resampling: input 32 kHz output 8 kHz
Using polyphase lowpass filter, transition band: 2742 Hz - 2839 Hz
Encoding PO_audio_kino.wav.wav to PO_audio-low.mp3
Encoding as 8 kHz 8 kbps single-ch MPEG-2.5 Layer III (16x) qval=2
Frame | CPU time/estim | REAL time/estim | play/CPU | ETA
1038/1040 (100%)| 0:05/ 0:05| 0:05/ 0:05| 13.322x| 0:00
average: 8.0 kbps
Everything looks right except that when I play the resulting file in xmms or
mgp123 it plays much too fast.
Could the headers on the mp3 be wrong? how do I check? they show up correctly
in xmms and mpg123.
mpg123 PO_audio-low.mp3
( ... )
Playing MPEG stream from PO_audio-low.mp3 ...
MPEG 2.5 layer III, 16 kbit/s, 11025 Hz mono
I know I used to play lower than CD quality sample rates.
Does anyone have an idea what is going on?
I have tried differing combinations of ecasound and lame with combinations of
-sr and -rate switches, to often similar results.
I am using the alsa drives from cvs for my audiofile 2496,
Thanks,
